JP Enhanced Bolt Features
The latest edition JP Enhanced Bolt is made from SAE 9310 high-grade steel. This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure and a life expectancy far exceeding Mil-spec C-158 bolts. SAE 9310 is the same type of steel used in the transmission gears of Formula One race cars, and the high-load application of a bolt assembly is ideal for this state-of-the-art material; the results of actual full-auto endurance torture tests prove it.

The design of the JP Enhanced Bolt addresses many other fine points, the most important of which is the utilization of a standard configuration extractor. Most users want the ability to replace extractors and other parts with commonly available mil spec parts instead of being dependent on proprietary parts that can be difficult to acquire. Therefore, the latest edition of the JP Enhanced Bolt accepts standard extractors, pins, and springs.

Why is the JP Rifles Enhanced 9310 Bolt Assembly better than the standard mil spec carpenter 158 bolt?
The standard mil spec C-158 (carpenter 158) bolt has a number of factors limiting its performance, not the least of which is that the life expectancy of such bolts is only about 6,000 rounds. In fact, standard bolts will start to show stress cracks on the locking lugs adjacent to the extractor cut after only 3,000 rounds. Cracking at the cam pin hole and weak extractor spring tension only add to the problems of the mil spec bolt. The material used in these standard bolts is also not the best choice by today's standards, but if you remember the old story that explains why mil-spec never dies, that applies here as well; they make them this way because they have always made them this way.
